DESCO 19788 Digital Surface Resistance Meter

The Desco 19788 Digital Surface Resistance Meter is an instrument designed to measure resistance point-to-point (Rtt) or surface to ground (Rtg) in accordance with ESD Association Standard ANSI/ESD S4.1. Its test funcitions include; Resistance measurement accuracy of ±10% (±20% for resistance values 1 x 10^11 and greater). Resistance range of <1 x 10^3 ohms to >1 x 10^12 ohms. Under load voltages of 10 and 100 volts ±5%. Electrification period of approximately 15 seconds. The Digital Surface Resistance Meter also measures ambient temperature and relative humidity. Specifications. Resistance Ranges: 1 x 10^3 - 1 x 10^12 ohms @ 10 Volts, complies with ANSI/ESD S4.1, 1 x 10^6 - 1 x 10^12 ohms @ 100 Volts, complies with ANSI/ESD S4.1. Accuracy: Resistance measurements within ±10% (±20% for resistance values 1 x 10^11 and greater), complies with ANSI/ESD-S4.1. Under load voltages of 10 Volts ± 5% and 100 Volts ± 5% exceed.

Carrier Wave (CW)
Carrier Wave or Continuous Wave is a sinusoidal signal without modulation.

Harmonic
A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc.

Noise Floor
Noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system.

Ripple
Ripple is the small unwanted residual periodic variation of the direct current (dc) output
